Alveolar vein

The alveolar veins include the inferior alveolar vein and the posterior alveolar vein. Both of the veins are also considered to be dental veins. The posterior alveolar vein drains blood from the lower teeth and jaw, and the posterior alveolar artery assists it in completing this function. The inferior alveolar vein can also drain blood to the pterygoid plexus. The posterior alveolar vein, on the other hand, works to drain blood from the molars and gums.  The alveolar vein is located in the mandibular canal. This canal is a horizontal chamber located inside of the ramus.  The alveolar inferior vein and the posterior alveolar veins are arranged in a plexus system, allowing them to empty blood out into a series of veins and muscles, including the pterygoid muscles, which serve as tributaries or drainages to the facial vein.
